A Software Quality Model for RPG

Abstract

The IBM i mainframe was designed to manage business applications for which the reliability and quality is a matter of national security. The RPG programming language is the most frequently used one on this platform. The maintainability of the source code has big influence on the development costs, probably this is the reason why it is one of the most attractive, observed and evaluated quality characteristic of all. For improving or at least preserving the maintainability level of software it is necessary to evaluate it regularly. In this study we present a quality model based on the ISO/IEC 25010 international standard for evaluating the maintainability of software systems written in RPG. As an evaluation step of the quality model we show a case study in which we explain how we integrated the quality model as a continuous quality monitoring tool into the business processes of a mid-size software company which has more than twenty years of experience in developing RPG applications.
